UO-EGS / UO-SGS Speed Switch Module

Description

UO-EGS / UO-SGS

U-ONE Generation II (LWL) – speed switch module

System solution U-ONE(-SAFETY)-LWL

  • Monitor overspeed and underspeed by means of 3 configurable speed switches equipped with positively driven relays
  • Easy configuration instead of complicated PLC programming
  • Switching capacity up to 250 VAC / 500 mA or 230 VDC / 180 mA
  • Options: Without SIL/PL certification (UO-EGS-R); combine up to 6 speed switches (= 2 modules)

Incremental encoders Overspeed switches

U-ONE Generation II (LWL) – speed switch module

The speed switch modules of the U-ONE(-SAFETY) second generation are electronic overspeed switches that monitor the defined speeds for overspeed and underspeed. They are equipped with hysteresis, a switching delay, a switching function dependent on the direction of rotation and the option of performing a switch test and can be parameterized as reliable error switches. The parameterization is carried out using input masks, meaning that complex SPS programming is not necessary. The modules are optionally available as certified up to SIL 2 / PL d.
